Conceptually pretty cool, but it gets old kinda fast. It introduces new mechanics at a decent pace, but I often found myself backtracking and re-backtracking just because I needed a specific ability I couldn't have at that point. This was really hurt by a lack of a map and a very repetitive structure. The end of the game also basically forces you to revisit every level to 100% it, which I found annoying. It just feels a bit shallow.
